Actually both my Superfly & HG Cuben have doors and having the 12 length on the Cuben with the door allows me to hang gear off the end of the hammock with a good expectation of it staying dry in a hard blow. That is something I like a lot. My DIY Jerry5 Hammock is 11 feet long and 12 on the tarp ... works for me.
